The 1978 Wimbledon Centre Court Riots

Jimmy Connors had just succumbed to the ice cool Swede, Bjorne Borg when the scuffle started. Strawberries were thrown, the ensuing fight spilled onto the centre court where the umpires chair was toppled, a ball boy was blinded by a flying tennis racket and a line judge was garrotted by the net cord......an event that never happened and is unlikely to.
If we were playing Blankety Blank and Terry Wogan asked you which word came after Football, how many of you would have put the word violence or hooligan? Cricket? People now use it as an excuse to dress up and wave 4's and 6's in the air. Rugby? Loads of singing....especially from the Welsh...who are the mirror image of the French ( good at cooking -rubbish at singing.)
Polo? Everyone gets up at half time and helps replace the divots. (Evidence based on watching Pretty Woman so may not be accurate.) Why does football generate the need for mindless violence?
A weekend where Portsmouth fans go on the pitch, Newcastle fans arrested after defeat in the Tyne Wear derby and Millwall fans, so desperate for a fight at Wembly that they pick on each-other.
24 years after Hillsborough can we say that things have improved in "the  beautiful game?"
Would Pele recognise it?
A friend related the story of his first trip to Stamford Bridge where a gentleman next to him dropped his business card and when it was picked up and returned, the businessman said that it was a card that he and his Associates would leave on a freshly beaten up opponent which read "You have been done over by the Chelsea Headhunters"....a little something to help as they awoke in hospital.

Do football "fans" emotions spill out in other areas?

Do they rip up seats in the cinema when Scar kills Mufasa?
Do they rip the 50" plasma screen off the wall at the results of Dancing on Ice?
I think not!
